If an animal or human develops its muscles or injures itself, these traits can be inherited by its offspring.
melamori03 [73]
False, because when the animal injures itself it is not part of the DNA so when the animal reproduces the trait is not passed down.  But the offspring can develop the same muscles or injuries as the animal did.

Which culture showed the most innovative building of dwellings?
Alenkasestr [34]

The correct option is B

The Folsom Culture is a name given by archaeologists to a specific Paleoamerican archaeological culture that occupied much of central North America. The term was coined by Jesse Figgins in 1927. It is possible that the Folsom culture has derived from the more primitive Clovis culture, and dates from a time between 9000 BC. C. and 8000 a. C.

Some of these sites exhibit evidence of more than 50 dead bison, although the Folsom diet also included goats, marmots, deer and rabbits. A Folsom field in Hanson, Wyoming, also revealed areas of possible settlements. The original site is Folsom, New Mexico, in Colfax County (29CX1), a place of slaughter near a marsh found in 1908 by George McJunkin, a cowboy, a former slave, who had lived in Texas as a child). The archaeological excavation was not carried out until 1926. In Mexico, in some places corresponding to the Lithic Stage, and especially to the Lower Cenolithic, folsom type arrowheads have been found, all in the Northern Altiplano. Among them we must mention Samalayuca (Chihuahua), La Chuparrosa (Coahuila), Puntita Negra (Nuevo León) and Cerro de Silva (San Luis Potosí).
